Abstract

The invention relates to the technical field of disposable hygienic products, and provides a preparation method of a moisture-absorbing breathable bottom film. The preparation method comprises the following steps: a. preparing modified viscose fibers; b, preparing modified polyester fibers; c, preparing spunlace non-woven fabric; d, preparing a lamination layer; and e. carrying out water repellent treatment. The problem that in the prior art, when the air permeability of the breathable film is large, the risk of urine leakage is likely to happen, and thus trousers outside a paper diaper get damp is solved.

Description

Technical field[0001]The present invention relates to the technical field of disposable hygiene, and more particularly to a method of preparing a moisture absorbent airbelled background.Background technique[0002]The leak-proof bottom layer of the existing diaper is mainly made of a breathable film or a breathable film and the bottom membrane non-woven fabric. The ventilation membrane generally uses a PE cast film or a PE blow molding film, and the base film-free fabric is basically spinning. Non-woven fabric and hot air nonwoven fabric. When the breathable amount of the breathable film is too small, the permeability of the diaper is poor, which may cause adverse effects of buttocks or cause an adverse effect such as urinary rash. In order to ensure the gas permeability of the diaper, the breathable amount of the breathable film is generally more done, but it is easy to have the risk of diaper, so that the trousers outside the diapers are tide.[0003]China Patent Application No. 20171...
